Carbon budgets at the component scale and their impacts on design choices: the façade as a case study

Marilyne Andersen, Thomas Bernard Paul Jusselme, Nazanin Rezaei Oghazi

In accordance with the Paris agreement, the Swiss Climate Strategy (SCS) defines the net-zero target to be reached before 2050, which demands for a thoughtful carbon budget allocation between the different contributors. Ongoing normalization tasks are curr ...

Evaluation of daylighting strategies based on their embodied carbon emissions: a first methodological framework and case study

Marilyne Andersen, Thomas Bernard Paul Jusselme, Nazanin Rezaei Oghazi

The impact of daylighting strategies on a building’s carbon emissions have so far been assessed mostly based on the building’s use phase and their resulting operational benefits, overlooking embodied carbon emissions of material production, construction, m ...

Life cycle efficiency of solar shading systems: a proof-of-concept

Marilyne Andersen, Sergi Aguacil Moreno, Thomas Bernard Paul Jusselme, Nazanin Rezaei Oghazi

Solar control strategies are essential for the glare control and decreasing cooling needs or overheating risks (in the absence of active cooling system), however, they come with their own embodied energy. With the carbon neutrality objective looking at the ...

Analysis and Visualisation of Decision Paths towards Reaching Environmental Impact Targets at Early-Design Stage

Émilie Nault, Sergi Aguacil Moreno, Thomas Bernard Paul Jusselme

Environmental impact objectives are commonly found in building performance labels and rating schemes. Anticipating a building’s impact from the conceptual design stage and identifying decisions that do not compromise its chances of reaching these targets i ...

Assessing the gap between a normative and a reality-based model of building LCA

Thomas Bernard Paul Jusselme, Endrit Hoxha, Stefano Cozza, Didier Albert Simon Vuarnoz

Recognized as a powerful methodology for the evaluation of environmental burdens, life cycle assessment (LCA) must be performed with close-to-reality inputs to be robust and accurate. However, the necessary real-world data is hardly available at the design ...

Surveying the environmental life-cycle performance assessments: Practice and context at early building design stages

Emmanuel Rey, Marilyne Andersen, Thomas Bernard Paul Jusselme

The international greenhouse gas agreements call for mitigations in the building industry. Thus, the number of scientific publications about life-cycle performance assessment (LCPA) follows an exponential trend since the 2000s. However, previous surveys hi ...

Data-driven method for low-carbon building design at early stages

Thomas Bernard Paul Jusselme

The Paris agreement on climate change called for carbon neutrality as of 2050. The built environment is one of the major contributors to the greenhouse effect, representing 39% of global emissions. As a result, this sector is targeted by green standards an ...

Carbon budgets for buildings: harmonising temporal, spatial and sectoral dimensions

Thomas Bernard Paul Jusselme

Target values for creating carbon budgets for buildings are important for developing climateneutral building stocks. A lack of clarity currently exists for defining carbon budgets for buildings and what constitutes a unit of assessment-particularly the dis ...

Office densification effects on comfort, energy, and carbon lifecycle performance: An integrated and exploratory study

Cédric Liardet, Laurent Liardet, Thomas Bernard Paul Jusselme, Endrit Hoxha

Generally, the environmental impacts of buildings are benchmarked per square meter as a functional unit. However, this practice prevents developing a user-centered approach in which performance is linked to real usage and not building size. Currently, the ...

Strategic environmental urban planning - A contextual approach for defining performance goals and informing decision-making

Marilyne Andersen, Émilie Nault, Sergi Aguacil Moreno, Thomas Bernard Paul Jusselme

Environmental performance objectives in terms of energy consumption and carbon emission targets can be found in various building norms and certifications schemes. These targets are often dependent upon the building program (e.g. office), but independent fr ...

Environmental impact assessment of Swiss residential archetypes: a comparison of construction and mobility scenarios

Emmanuel Rey, Sophie Lufkin, Sergi Aguacil Moreno, Thomas Bernard Paul Jusselme, Endrit Hoxha, Judith Elisa Drouilles

Environmental performance assessment of the built environment tends to focus mostly on operational final energy consumption of buildings located within a specific context. Such a limited scope prevents broader usability of findings in practice. In Switzerl ...

Design guidance from a Data-Driven LCA-Based Design method and tool prototype

Emmanuel Rey, Marilyne Andersen, Thomas Bernard Paul Jusselme

As of 2020, every new building in the European Union will have to reach the nearly Zero Energy Building (nZEB) performance. However, building nZEB will not be sufficient to reach carbon neutrality in 2050 as required by the last IPCC report: indeed, even n ...

Life-Cycle Assessment as a decision-support tool for early phases of urban planning: evaluating applicability through a comparative approach

Marilyne Andersen, Émilie Nault, Thomas Bernard Paul Jusselme, Katarina Slavkovic

While ambitious environmental objectives are being set for new constructions in Switzerland, the assessment of urban-scale projects and comparison of their performance to national targets are made possible by a growing number of life-cycle assessment (LCA) ...

Improving life cycle-based exploration methods by coupling sensitivity analysis and metamodels

Thomas Bernard Paul Jusselme

Exploration methods combine parametric energy assessments and data visualization to support building designers at early design stages. When exploration methods come to Life-Cycle Assessment (LCA) and the Global Warming Potential (GWP) assessment, a larger ...

Temporal variations in the primary energy use and greenhouse gas emissions of electricity provided by the Swiss grid

Thomas Bernard Paul Jusselme, Didier Albert Simon Vuarnoz

It is a frequent practice nowadays to use mean annual conversion factors (CFs) when performing life-cycle assessment (LCA) of processes and products that use electricity supplied by the grid. In this paper, we conduct an hourly assessment of the greenhouse ...

Usability assessment of building performance simulation tools: a pilot study

Marilyne Andersen, Thomas Bernard Paul Jusselme, Stefano Cozza

Due to climate change, the built environment is facing increasingly strict environmental targets. Thus, architects are challenged to design evermore high-performing buildings, a task for which they can no longer depend solely on their experience and intuit ...

Neutral global warming potential target of electricity storage as threshold for greenhouse gas emission mitigation in buildings

Thomas Bernard Paul Jusselme, Didier Albert Simon Vuarnoz

Coupling photovoltaic (PV) systems with energy storage (ES) in buildings, enables to increase the building’s energy autonomy and the self-consumption of onsite renewables. ES increases nonetheless the life cycle environmental impact of the stored energy. A ...

Findings from a survey on the current use of life-cycle assessment in building design

Emmanuel Rey, Marilyne Andersen, Thomas Bernard Paul Jusselme

The built environment is facing environmental regulations more ambitious than ever before. In Europe, a law will lead all new buildings to the Nearly Zero-Energy performance level. However, even if a building does not have any energy consumption for its op ...
